STOP MECHANISM FOR STORE-SERVICE APPARATUS.

SPEGIFICATION'forming part of Letters Patent No. 615,338, dated December6, 1898.

Application filed June 4, 1898. Serial Not 682,585. (No model.)

To all whom it may concern.-

Be it known that- I, SAMUEL W. BARR, of Mansfield,in the county ofRichland and State of Ohio, have invented certain new and use fulImprovements in Stop Mechanism for Store-Service Apparatus; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in stop mechanism forstore-service apparatus, and more particularly for use on doublewirelines, the object being to provide a simple and effective device foryieldingly stopping the car or carrier at the station.

With this end in view my invention consists in certain novel features ofconstruction and combinations of parts, as will be hereinafter morefully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a View of myimprovement in its operative position on a double-line wire. Fig. 2 is asectional view of the slide, and Fig. 3 is an enlarged detached view ofthe buffer.

A represents a hanger provided at its lower end with alaterally-projecting arm 2 and at its upper end with a similar arm 3,which latter is preferably removably secured to said hanger. To theouter ends of these arms is connected a guide-rod 4:, on which latter aslide 5 is adapted to move. This slide 5 is provided near its innerlower end with an antifriction-roller 6-, while its opposite lower endis connected with the propelling trackwire 7. The upper inner end ofsaid slide is connected to one end of the operating-cord 8, which latterpasses over a pulley 9, mounted in a recess formed in hanger A near itsupper end and terminating at a convenient point below thelaterally-projecting arm 2.

B represents a buffer comprising a frame 10, a pair of arms 14.,depending from said frame, each of said arms being provided with abearing 11, a stop-rod 12, mounted to slide in said bearings, said rodbeing provided with a head 13, having a yielding plug 15 locatedtherein, and a coil-spring 16, mounted on said stop-rod for the purposeof controlling its movement. This spring is of considerable length andresilience and encircles that portion of the stop-rod located betweenthe rear end of head 13 and the adjacent arm 14.

The buffer above described is supported by the arm 2 and the stationarytrack-wire 17, the connection being effected in the manner shown.

In the drawings I have shown but one station; but it is my intention toemploy the stop mechanism at each end of the line, and when so appliedit will be apparent that when the car or carrier arrives at either endof the line it will be cushioned and brought to a stop without impartinga serious pounding to car or carrier. As soon as the car or carrierstrikes the end of stop-rod 12 the spring 16 will be immediatelycontracted and allow said stop-rod to move rearwardly until the force ofthe car is overcome, after which the spring will gradually expand to itsnormal position, carrying with it the stop-rod and the car or carrier.The forward movement of the stoprod is limitedby the pin 18.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, 18-- 1. In a double-wire cash-carrierapparatus, the combination with a fixed support and a movable track vireconnected therewith, of a frame attached at one end directly to thelower end of said support, a fixed track-wire attached to the other endof said frame and a yielding stop-rod mounted to slide in said frame,substantially as set forth.

2.The combination with a supporting device, a lower or stationary wiresecured to said supporting device, a vertically-movable slide on thesupporting device, an upper or movable propelling track-wire attached tosaid slide and a car having wheels between which said track-wires pass,of a yielding stop-rod connected with the said supporting device in lineof travel of the car, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

SAMUEL W. BARR.
